About this replacement
AnexTEX moboDA A3360 — 3.7V Li-Polymer Replacement Battery
This 3.7V, 1500mAh lithium-polymer cell replaces the original battery in the AnexTEX moboDA A3360 PDA. It fits the A3360 handheld directly and matches the original voltage and capacity spec. The A3360 is a Pocket PC device — getting the cell chemistry right matters for the BMS handshake and stable power delivery to the processor and radio.
- moboDA A3360 fit: The A3360 runs on a single lithium-polymer cell at 3.7V nominal. There is no multi-cell configuration on this platform. The BMS in the device monitors cell voltage directly, so a mismatched cell voltage causes the device to report incorrect charge states or refuse to boot.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a PDA test rig. The BMS accepted the cell without error flags, and the charge controller reached full cutoff at 4.2V as expected for Li-Polymer chemistry.
- RAM data protection before swapping: Perform a full ActiveSync or Windows Mobile Device Center sync to the host computer before removing the battery. The A3360 holds open application state and unsaved data in volatile RAM powered by the main cell — cutting power without syncing first loses that data permanently.
Why the moboDA A3360 won't boot after a new battery is installed
A freshly shipped Li-Polymer cell typically arrives at 30–50% charge. The A3360 boot sequence requires the cell to sit above a minimum voltage threshold before the processor will initialise. If the device shows nothing on screen or loops at the boot logo, the cell voltage is too low to complete POST. Charge the battery in the device for at least 30 minutes before attempting to power on. Once the cell clears the minimum threshold — around 3.5V — the boot sequence completes normally.
A3360 showing shorter battery life after switching to warehouse scanning tasks
The scanner LED and wireless radio on the A3360 draw significantly more current than standard PDA use. In active scanning sessions with the backlight on and Wi-Fi or Bluetooth connected, the cell discharges far faster than during note-taking or calendar tasks. This is not a battery fault — it reflects real current draw that the original battery also experienced. To extend time between charges in scanning use, reduce backlight brightness and disable wireless radios when not actively syncing data.
